SDZ-520 series top-loading (bottom mounted) Magnetic flap level gauge Overview; 
 Of SDZ-520 series top-loading (bottom mounted) type liquid level gauge of the magnetic flap opening position used in underground containers installed level gauge with built-in type level UIZ is cheap, can be applied to the flammable explosive, toxic, corrosive and volatile environment, widely used in oil tanks, underground storage tanks, tank containers and food, chemical, fertilizer and other industries, coupled with related accessories in the level gauge alarm and control signals output function. 

 SDZ-520 series top-loading (bottom mounted) Magnetic flap level meter main technical indicators: 

 A range (mm): 300 ~ 6000 
 2 medium density (g/cm3): 0.5 ~ 2 
 3 Operating Temperature (℃): -40 ~ 350 
 4 pressure level (MPa): ≤ 32 
 Measurement accuracy (mm): ≤ ± 10 

 SDZ-520 series top-loading (bottom mounted) Magnetic flap level gauge works 
 The product by the body (from the upper and under catheter composition), shutter box (by the red, white and color magnetic flap), float (magnets, ejector, and pontoon), the structure shown , works as follows: float container (different media and pressure for development), next with the liquid level changes in the catheter fluctuate through the mandrel so that the magnet to move up and down on the catheter, prompting the outside flap turning and red, white and color to indicate the liquid height. 
 SDZ-520 series top-loading (bottom mounted) Magnetic flap Level Gauge features 
 Can be installed in the container upper or lower level gauge of the form of an unfit side openings in the container and container around very little room for 
 2, applies to the viscosity of the liquid medium 
 3, the display's viewing direction can be arbitrarily changed 
 4, the installation of Level Switch transmitter control switch without stop installation and adjustment at any time. 
 5 If the power is interrupted, the scene switches. Also not affected, and high accuracy. 
 6, every 10 minutes plus the different colors of liquid, liquid easy identification. 
 SDZ-520 series top-loading (bottom mounted) Magnetic flap level gauge selection of Notes 
 An anticorrosive nominal pressure ≤ 1.0MPa. 
 The level gauge has some blind spots, so read the liquid level height should be coupled with the blind spot value of compensation (the level gauge factory, the ruler scale of zero to migrate to the actual value). 
 3, the level gauge measuring range over 5 m, or affect the level of reliable fastness. 
 4, installation flanges, the level meter factory commonly used raised face size reference (HG21592-97) manufacturing. 
 SDZ-520 series top-loading (bottom mounted) Magnetic flap level gauge installation and maintenance 
 1, level meter to protect the catheter and the main conduit must be kept vertical 
 2, the connecting rod is not bent, you must insert straight 
 3 After installation, you need display turned column using magnets to guide a zero display white, red below zero.
